The L129 Series Lube Level Switchgauge is a combination lube level indicating gauge
and adjustable low and high limit switches. It provides protection against low oil level or
high level caused by overfill or fuel or water seepage into the crankcase.
A 6-3/4 inch (171 mm) deep sight gauge allows you to check the condition and level of
your oil without shutting down the equipment.
Fingertip-adjustable limit contacts, thru 4-7/8 inch (122 mm) range, make it simple to set
high and low limit contacts. If the float touches the high or low limit contact, a normally
open circuit will be completed which can activate alarms and/or shut down the
